New in ACS SynBio: led by Dennis Bolshakov, we used the awesome power of yeast to define how expression levels, noise, and sequence program the dynamics of synthetic protein waves, allowing us to genetically encode new cellular timescales stable over generations!

Thrilled to share our work on the 🔥 single-celled predator Podophrya collini, which rewires its cell morphology to hunt more efficiently. Huge thanks to our amazing team—Amy, Lauren, Omaya, Marine, Mari, and especially Scott—for making this shine! ✨
How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926

Barred owls are native to Wisconsin, but invasive out west. New UW–Madison research reveals they’re preying on at-risk species and disrupting entire ecosystems as they spread down the West Coast.
The barred owl’s westward migration threatens other species and a whole ecosystem, UW researchers find
A new study shows that the invasive predator feeds on 29 species given special conservation status by federal and state governments.

I wrote a quick-start guide for people to replicate this across the country. It was, in our experience, a very effective way to get real action in a short amount of time.

People are willing to talk to scientists! And when you provide everything, they are happy to contact their reps too. Try it!

this 👇 makes my point. Industry, speak up already. you arent shy when it comes to protecting your profits and privileges? so why not protect your vital pipeline?
The war on science in the US is already having an effect on private sector research like AlphaFold. Bears repeating but the private sector builds on top of things created by academic research for the public good. This hurts everyone.

Friendly amendment: May was brutal for the US. Trump sowed mass fear and confusion with a slew of illegal and unconstitutional orders. He faced no consequences other than being asked nicely to please stop, and so of course he continues to do destroy our country with this exact same playbook.
Stunning. May was brutal for Trump in federal court: 96% loss rate ⚖️. Even GOP-appointed judges have ruled against the admin 72% of the time. District courts are doing their job defending the Constitution. Soon the Supreme Court may be the only court unwilling to defend the rule of law.

With the shifting regulatory climate (i.e., antivax ratfuckery), Moderna has withdrawn their application for their eagerly anticipated COVID-flu combo vaccine. This vaccine offered better protection than getting each shot separately.
